Diagnosing relativistic particle acceleration in AGN jets
(AIP, 2017)Mildly relativistic, oblique shocks are generally considered to be among the most plausible sites of relativistic particle acceleration and the subsequent production of strongly variable, polarized multi-wavelength emission ... -
A diagnostic biomarker profile for fibromyalgia syndrome based on an NMR metabolomics study of selected patients and controls
(BioMed Central, 2017)Background: Fibromyalgia syndrome (FMS) is a chronic pain syndrome. A plausible pathogenesis of the disease is uncertain and the pursuit of measurable biomarkers for objective identification of affected individuals is a ... -
Diagnostic tests for the distribution of random effects in multivariate mixed effects model
(Taylor & Francis, 2016)Fourier methods are proposed for testing the distribution of random effects in classical and robust multivariate mixed effects models. The test statistics involve estimation of the characteristic function of random effects. ... -
Dialogues of memory, heritage and transformation: re-membering contested identities and spaces in Postcolonial South African and Zimbabwean White writings
(Taylor & Francis, 2016)The protean and contested symbols of Zimbabwean literature remain the land and invented heroes, including a hagiographic iconisation of shrines, best seen in the Zimbabwe ruins, the Zimbabwe Bird and the national heroes’ ... -
Diamond formation by carbon saturation in C–O–H fluids during cold subduction of oceanic lithosphere
(Elsevier, 2014)Microdiamonds in garnet of graphite-free ultrahigh pressure metamorphic (UHPM) rocks from Lago di Cignana (western Alps, Italy) represent the first occurrence of diamond in a low-temperature subduction complex of oceanic ... -
Diamond precipitation from ascending reduced fluids in the Kaapvaal lithosphere: thermodynamic constraints
(Elsevier, 2012)Previous research has shown that the Kaapvaal lithospheric mantle is generally reduced and characterised by a decreasing redox state with increasing depth. As a consequence, CO- H fluids in the Kaapvaal lithospheric ... -
Diaphragmatic-intercostal breathing and the occurrence of gastroesophageal reflux disease in singers
(2014)This article was inspired by our awareness of an increasing number of voice students and professional singers who specialize in Western art music and who present with symptoms relating to gastro-esophageal reflux disease ... -
Diatom communities in the High Arctic aquatic habitats of northern Spitsbergen (Svalbard)
(Springer, 2017)As High Arctic environments are particularly sensitive to global and regional climate changes, a growing number of studies have focused on that region. It has been shown that living and fossil diatoms can be successfully ... -
A diatom functional-based approach to assess changing environmental conditions in temporary depressional wetlands
(Elsevier, 2017)Functional-based assessments to identify the effects of human-induced disturbances on diatom communities are increasingly used. However, information on the response of functional groups to natural disturbances in temporary ... -
Diatom teratologies as biomarkers of contamination: are all deformities ecologically meaningful?
(Elsevier, 2017)Contaminant-related stress on aquatic biota is difficult to assess when lethal impacts are not observed. Diatoms, by displaying deformities (teratologies) in their valves, have the potential to reflect sub-lethal responses ... -
Diatoms as indicators of historical water quality: A comparison of samples taken in the Wemmershoek catchment (Western Province, South Africa) in 1960 and 2008
(WRC (Water Research Commission), 2014)Historical diatom records provide a means of retrospectively determining water quality and inferring ecological condition in rivers and streams. In this study we re-sampled sites originally sampled 48 years previously. We ... -
Diatoms as water quality indicators in the upper reaches of the Great Fish River, Eastern Cape, South Africa
(Natl Inquiry Services Centre Pty Ltd, 2015)This study focused on the spring-fed upper reaches of the economically important Great Fish River with the aim of determining if diatoms could be used for biomonitoring in semi-arid conditions in southern Africa. Five ... -
Did adultery mandate divorce? A reassessment of Jesus' Divorce Logia
(Cambridge University Press, 2015)This paper argues that Matthew's so-called exception clauses to the prohibition of divorce (5.32; 19.9) make explicit what was already implicit in versions without them: that adultery required divorce. While biblical law ... -
Did bank capital regulation exacerbate the Subprime Mortgage Crisis?

Did brightest cluster galaxies experience more than one star formation epoch?
(Cambridge University Press, 2012)We use the full spectrum fitting ability of ULySS, with the Pegase.HR stellar population model to fit the observed spectra of 40 brightest cluster galaxies in order to determine whether a single or a composite stellar ... -
Did muthi, ritual and witchcraft murders happen only in the Dark Medieval Ages of South Africa? Think twice!
(WordPress, 2016)Background: Muthi, ritual and witchcraft murders seem to be inherent pathologies of a certain section of the South African population. Various determinants contribute to the generation and endurance of such behaviour. These ... -
Die 2001-omdigting van die Psalms na vyf jaar
(SAKOV, 2006)In 2001 a new version of the Afrikaans Psalter was published. It contains 150 hymns in a strophic version by T.T. Cloete, eight by Lina Spies, two by Andries Breytenbach, two by Antjie Krog and one by Elsabe Kloppers. This ... -
Die aandeel van Potchefstroom in Voortrekkerstaatsvestiging
(Suid-Afrikaanse Akademie vir Wetenskap en Kuns, 2013)While Potchefstroom did not figure in the planning of Voortrekker state establishment, a variety of unforeseen factors led to its founding. These include Potgieter’s aversion to settlement in Natal and his consequential ... -
Die aanspreeklikheid van 'n insolvente maatskappy en die likwidateur van 'n insolvente maatskappy vir vergoeding as gevolg van omgewingsbenadeling
